ASTM D1875-03
(Test Method)Standard Test Method for Density of Adhesives in Fluid Form
Standard Test Method for Density of Adhesives in Fluid Form
SIGNIFICANCE AND USE
This test method is particularly applicable where the fluid has too high a viscosity or where a component is too volatile for a specific gravity balance determination.
SCOPE
1.1 This test method covers the measurement of density (weight per gallon) of adhesives, and components thereof, when in liquid form.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
